To all whom it may concern:

Be it known that I, BERNARD HIPPOLYTE CHAMEROY, a resident of Vesinet, in the Republic of France, have invented a new and useful Improvement in Oil-Cans, (for which I have obtained patents in France, No. 228,329, dated March 2, 1893; in Germany, No. 74,800, dated J une 19, 1893, and in Belgium, ,No. 105,112, dated June 17, 1893,) of which the following is a specification.

This invention relates to what are known as squirt 'oil cans.

The improvement consists in the combina tions hereinafter described and claimed.

Figure 1 of the accompanying drawings represents a central section of an oil can constructed according to my invention. Figs. 2 and 3represent in plan, details of the valves. Fig.4 is a side view illustrating how, with an oil can embodying my invention, parts of machinery at a great height or accessible only from below may be oiled in an upright position.

Similar letters of reference designate corresponding parts in all the figures.

A designates the reservoir of the can which may have any form whatever.

B is the lower compartment which communicates on the one part with the reservoir by a contracted orifice b of such size and so arranged as only to permit a slow flow of the liquid contained in B when the can is inverted, and on the other part with a pump 0 oy an orificeb' in the bottom of the latter.

The barrel of the pump 0 is constituted by a cylinder arranged obliquely within the reservoir A. It is affixed at its lower part to the false bottom B" which constitutes the partition between the lower compartment B and the upper compartment or reservoirA. The said cylinder projects through the upper part of the can outside of which it is fitted with a cap 0 which has in it a central hole large enough for the passage of the'piston-rod D. This rod is terminated at its upperextremity by a button D at a certain distance from which it is enlarged to form ashoulder which limits the upward movement of the piston by coming in contact with the interior of the cap 0. The coil spring D which bears at one end against the bottom of the pump and at the other against the piston tends to force the latter upward as far as permitted by the shoulder on the rodD. y

The suction valve is represented as consisting of a ball e kept closed to its seat around the orifice b bya light spring, a very simple mode of construction consisting in using as this spring a suitably curved prolongation D of the return spring D of the piston. Although this arrangement may be preferable, the closing spring of the valve may be constituted by a tongue 6 (Fig. 2) formed by cutting an annular slit in a thin metal disk .e'; it will be seen that this tongue is only connected by a narrow neck to the outer rim of the disk which gives it sufficient elasticity;

this disk is aflixed at its margin'above the valve seat. The valve e might, however, be replaced by a flap valve cut from the disk of leather as shown in Fig. 3. This valve might be keptto its fiat seat by means of alight spring such as that shown in Fig.2.

From the pump barrel (3 above the partition or false bottom B a discharge pipe F leads to .a socket F which constitutes the head of the can which is centrally bored.

The upper face of this socket serves as the seat of the discharge valve g which may be like the suction valve e. The drawings represent a ball valve held to its seat bya spring g analogous to that shown in Fig. 2. The socket F is screw-threaded to receive the unioncoupling H which serves to attach the discharge spout H, andleather rings g assure the staunchness of the joints at this point. Arrangement must be made to permit the entrance of airto the can and this may be obopening tight enough to form a sufficiently staunch joint which will prevent the escape of oil but not tight enough to prevent the entranceof air.

What I claimas my invention is- 1. In an oil can, the combination with a principal compartment or reservoir furnished with a spout, a lower compartment communicating with said principal compartment through a contracted orifice, a pump barrel having an opening to the said lower compartment and in which is a piston and a spring for forcing said piston outward, a suction tained by screwing up the'cap J of the filling I valve arranged within said pump barrel at said opening and constituted by a ball held to its seat bya prolongation of the said spring, and a discharge valve situated at thebase of the discharge spout and arranged to be always closed when the pump is not in operation and to be more or less opened according as the pump piston is pressed inward more or less forcibly, substantially as herein described.

2. In an oil can, the combination with a principal compartment or reservoir furnished with a spout, a lower compartment communicating with said principal compartment through a contracted orifice, a pump barrel having an opening to the said lower compartment and in which is a piston and a spring for forcing the said piston outward, of a suc-
